CBB Decanter centrifuges are horizontal separators for separation of two or three phases contained in a product of wastewater treatment and/or industrial and/or food product origin.
These machines can be seen as particular clarifying tanks, with only the difference of the presence of centrifugal force that improves time and efficacy of separation. In fact, in a traditional clarifying tank, the particles are exposed to an acceleration equal to gravity acceleration (g=9,81 m/s2). In CBB decanters such an acceleration is equal to centrifugal acceleration that can reach values comprises between 3000 and 5000 times than gravity acceleration.
All working cycle of CBB decanter is managed and controlled through a DPC card (Decanter Process Controller), that is a dedicated electronic designed, manufactured and programmed (Assembly language) for the optimization of separation process. In this way, the entire process can be adapted to the different necessities of the customer for his/her full satisfaction.
14 REASONS TO CHOOSE A CBB DECANTER:
- Working cycle managed automatically from dedicated electronic DPC (Decanter Process Controller)
It allows to work in safety taking maximum advantage of all the potentialities of the CBB decanter; - Twenty-year experience in sludge separation processes.
It assures satisfaction in most cases of requests and needs of the customer. - Coverings divided in 4 parts, extendable and can be inspected singularly
It simplifies operator job for possible maintenance of rotating part; - Rotor group easily extractable from on high
It simplifies operator job for possible maintenance of rotating parts; - Solid discharge bushes easily accessible and replaceable from the external even with closed coverings.
It simplifies operator job for possible control and replacement; - Liquid discharge level plates easily accessible from the external even with closed coverings
It simplifies operator job for possible control and regulation; - Sludge scraper shovel assembled on rotor group
Prevent sludge storage on walls of solid discharge of the machine; - Transmission group with possibility of energy recovery during working phase
it allows a reduction of energetic consumption of decanter CBB; - Screw with blockage disc
It increases working capacity of the decanter and improves separation process; - Flanges and bowls obtained from melting and with relevant and strong sections
It improves resistance and homogeneity of bowl structure; - Base structure of screw in solid steel
It improves resistance, stiffness and lasting of the screw; - Hydraulic actuators for coverings opening
It simplifies operator job for possible maintenance of rotating parts; - Damping system of vibrations fixed on framework base of the decanter
It restricts vibration transmission to the ground; - Possibility of remote assistance
It reduces waiting time for resolution of possible problems; - Technical interventions within 24 hours (in Italy or 48 hours abroad) from possible arising problem
Speed intervention for resolution of possible arising problems;
MAIN COMPONENTS OF CBB DECANTERS:
STRUCTURE
It sustains all rotor group of decanter.
LIQUID DISCHARGE
It has double function of protection from possible dangers due to the presence of rotating parts and convey of products of liquid separation.
SOLID DISCHARGE
It has double function of protection from possible dangers due to the presence of rotating parts and convey of products of solid separation.
CENTRAL COVERING
It has double function of protection from possible dangers due to the presence of rotating parts and convey of washing product
SUPERIOR CARTER
It takes the role of protection from possible dangers due to the presence of rotating parts.
BOWL
At its internal sludge to treat is conveyed and there is the separation of the different phases.
SCREW
It conveys separated solid to outlet openings of the bowl.
TRANSMISSION GROUP
It transmits the rotation to the screw and to the bowl through belt transmission;
